What is the curved side in a cylinder like?
Answer and explanation
Correct answer: Made of a curved round surface
The governing concept is the structure of a cylinder as a three-dimensional form. A cylinder has two parallel, congruent circular bases joined by one continuous curved lateral surface. If a rectangular sheet is rolled and its opposite edges meet, that rolled sheet represents the cylinder’s curved side; it has no straight corners like a square or triangle. Option C is correct because the lateral part bends smoothly around the circular bases and forms a rounded surface. Option A is incorrect because three corners describe a triangular idea, option B ignores the continuous curvature, and option D is impossible because every solid form has a surface. Recognising bases and the curved lateral surface helps identify a cylinder in drawing and observation.
